HPE Synergy 20G Interconnect Link Module
The HPE 779218-B21 is a satellite module for composable infrastructure. It extends fabric connectivity across multiple Synergy frames using a primary/satellite architecture. This device server consolidates data centre network connections and reduces the need for fixed interconnect ratios in each frame. It is built for organisations scaling rack-level network bandwidth.
Verify Synergy frame compatibility
Before ordering, confirm that your existing Synergy frames support satellite module expansion. The module requires a primary module with intelligent networking capabilities to extend connectivity to satellite frames. Check that your current fabric architecture can integrate a 20Gb satellite link for disaggregated resource pooling. Ensure rack-scale design aligns with this primary/satellite topology.
Sustained load consolidates connections across
Under continuous operation, the module maintains a fluid pool of network resources across multiple frames. It reduces hardware components at the aggregation layer while simplifying fabric management at scale. The satellite architecture delivers consistent 20Gb connectivity to compute modules without the port consumption of traditional top-of-rack switches. This design supports ongoing composable infrastructure demands.

Questions about this item
What comes in the box with the 779218-B21 and what must be purchased separately?
The 779218-B21 Synergy 20G Interconnect Link Module is supplied as the module itself. HPE Synergy frames, compute modules and the primary interconnect module are sold separately.
How do I choose between the listed versions or capacities for this module?
The 779218-B21 is a single part number with a 20Gb interconnect speed; no alternative versions or capacities are offered for this model.
What does the 20Gb figure mean when the module is installed in a live Synergy frame?
The 20Gb rating provides 20Gb connectivity from satellite frames to Synergy Compute Modules, extending the composable fabric across up to two additional frames.
